Whether it's ventilation or pipeline,   expansion bellows   play a very crucial role during the working efficiency of a variety of industrial sectors. They are touted to be the most flexible instrument for many different types of industries. These circular tubes are too flexible to extend or compress on pressure. Besides, they also have sufficient capabilities to take much heat, and can stay in good condition for a long time. Made out of plastic, steel, rubber or fiber, the material of the expansion bellows normally depends upon their purpose.   What are expansion bellows made of? A bellow is built of a series of one or more convolution, including the shape of the convolution crafted to sustain the internal pressures of the pipe, but it’s too flexible to accept the lateral, axial, or/and angular deflections. In other words, the expansion bellows are made so that they are able to withstand pressure available inside the pipe. They are, nonetheless, made to be too flexible so that the

Axial expansion joints are expansion joints that absorb mainly longitudinal movements axially along a straight section of pipe. Axial expansion joint flared flanges and guide sleeve   Advantages of axial expansion joints ► Simple means of compensation ►Smaller space requirements ►No alteration of flow movement ►Movement possible in any direction ►No redirection of pipe work required ►Low unit costs   Disadvantages of axial expansion joints ►High axial forces at higher pressures ►Strong fixed points and good axial pipe guides required ►Small and medium movement absorption ►For large expansion movements several axial expansion joints are required ►On long stretches many fixed points and pipe guides are required   Axial expansion joint variants Connection parts Axial expansion joints can be manufactured with weld ends, fixed flanges or swivel flanges or combinations thereof, depending on customer requirements Guide tubes To avoid abrasion and turbulence (e.g. at high flow rates in pipe wo

Hose connectors are used to connect pumps to piping, and many problems can occur at this connection unless the proper hose connectors are in place to handle them. At this critical connection, piping misalignment, thermal expansion and other problems can occur that can lead to seal leaks, coupling problems and bearing issues. The right pump connector will also isolate pump vibration, which can build up and cause great harm if not managed through good connectors. The root cause of all these problems is the need to handle the nozzle load to reduce the pressure at that single point, and that's where flexible pump connectors come in. To disperse the pressure at the pump and pipe connection, there are four main types of pump connectors offered, each of which is a good solution for a specific type of situation. Rubber joints  perform very similarly to expansion joints and are ideal for absorbing noise and absorbing vibration, but are not the best choice for chemical or high temperature ap
